I think what we're looking at here is the level of service and timeliness of service to meet our sales commitments. That's what we're really talking about.
I would say that in the trucking business if you're not getting that timely service from company A, because there are more than one of them you would go to company B. That's not always the same option here because of the distance. The rail lines are apart in the prairies, for example.
An anecdote for you is that we've worked hard to secure market access and negotiate trade agreements with all of these countries. When Pulse Canada was down in Colombia and we'd just signed a deal there, we were looking forward to increased exports to Colombia, and the Colombians said they weren't sure they'd actually buy anything more from us because they couldn't get reliable enough delivery of product on time.
